The Initial Management of Chronic Pelvic Pain

Definition and Context

Chronic pelvic pain (CPP) is intermittent or constant pain in the lower abdomen or pelvis of at least 6 months' duration, not occurring exclusively with menstruation or intercourse, and not associated with pregnancy. It is a symptom, not a diagnosis. CPP presents in primary care as commonly as migraine or low back pain and affects roughly 1 in 6 adult women.

Assessment Approach

Adequate time must be allowed at initial assessment — women need to feel heard and believed, and many present wanting an explanation rather than immediate treatment. The multifactorial nature of CPP should be explained from the outset, and management planned in partnership with the woman (Grade B).

History: ask about the pattern of pain, its relationship to bladder/bowel symptoms, psychological factors, and the effect of movement and posture. Screen for 'red flag' features (rectal bleeding, new bowel symptoms over age 50, new pain after menopause, pelvic mass, suicidal ideation, excessive weight loss, irregular vaginal bleeding over age 40, postcoital bleeding), and directly but sensitively ask about past or present sexual assault or intimate partner violence. A 2–3 cycle pain diary can help identify triggers. Irritable bowel syndrome (IBS) can be diagnosed on symptoms alone using Rome III criteria, with a positive predictive value of 98% (Grade B).

Examination: abdominal and pelvic examination looking for focal tenderness, enlargement, distortion/tethering, or prolapse; myofascial trigger points in the abdominal wall or pelvic floor; and tenderness of the sacroiliac joints or symphysis pubis suggesting a musculoskeletal cause.

Investigations: screen for Chlamydia trachomatis and gonorrhoea if pelvic inflammatory disease (PID) is suspected; offer STI screening to all sexually active women with CPP (Grade D). Transvaginal scanning (TVS) is appropriate for adnexal masses and diagnosing adenomyosis (Grade B); MRI's role in detecting small endometriotic deposits is uncertain. Check serum CA125 if bloating, early satiety, pelvic pain, or urinary urgency/frequency occur persistently (>12 times/month), particularly over age 50. Diagnostic laparoscopy, historically the "gold standard," should now be regarded as a second-line investigation, used only if other therapeutic measures fail (Grade D) — it carries an estimated 1 in 10,000 risk of death and ~2.4 in 1,000 risk of visceral/vascular injury.

Differential Diagnosis (Contributory Factors)

CPP is usually multifactorial rather than attributable to a single pathology: endometriosis/adenomyosis (suspect when pain varies markedly with the cycle, Grade D), adhesions (fine adhesions have no proven causal role; dense vascular adhesions may warrant division), IBS and interstitial cystitis (common comorbidities, Grade C), musculoskeletal pain/trigger points (Grade C), nerve entrapment (e.g. post-Pfannenstiel scar, Grade D), and psychological/social factors including depression, sleep disturbance, and a history of abuse (Grade B — enquiry should always be made).

Initial (Non-Surgical) Management Ladder

1. Cyclical pain: offer a 3–6 month therapeutic trial of hormonal treatment (combined oral contraceptive, progestogens, danazol, GnRH analogues, or the levonorgestrel-releasing IUS) before diagnostic laparoscopy (Grade B).
2. Suspected IBS: trial of antispasmodics (Grade A) and dietary modification (Grade C).
3. Analgesia: offer appropriate analgesia regardless of whether other treatment has started — regular NSAIDs ± paracetamol, compound analgesics (e.g. co-dydramol); opioids are generally inadvisable for regular use in this setting; adjuvants (amitriptyline, gabapentin) for neuropathic pain features.
4. Non-pharmacological adjuncts: TENS, acupuncture, and other complementary therapies may help some women.
5. Referral: if pain remains poorly controlled, refer to a pain management team or specialist pelvic pain clinic; refer to gastroenterology, urology, GUM, physiotherapy, psychology, or psychosexual counselling where a specific non-gynaecological component is identified.
6. Laparoscopic uterosacral nerve ablation (LUNA) is ineffective and should not be offered.

High-Yield Exam Points

• CPP = symptom of ≥6 months' duration, not a diagnosis; usually multifactorial.
• Hormonal therapeutic trial (3–6 months) for cyclical pain comes before diagnostic laparoscopy (Grade B).
• Diagnostic laparoscopy is now second-line, not the gold standard — reserve for failed medical therapy (Grade D).
• IBS can be diagnosed on Rome III symptom criteria alone (PPV 98%, Grade B) — no need to over-investigate.
• LUNA is ineffective for CPP — a classic exam distractor.
• Always screen for red flags and ask directly about abuse/IPV.
• CA125 is indicated for persistent bloating/early satiety/urgency/pelvic pain (>12×/month), especially over age 50, to exclude ovarian malignancy.
